United States Patent misses QUATE'RNARY re -arenas John D. Zech, Wilmington, Deh, assignor to Atlas Powder Company, Wilmington, "Del a corporation of Delaware No Drawing. Application July 14, 1953, m n! N9. 36,8,Qlll5 6 Claims. (Cl. 260-2471) This invention relates to new organic morpholinium phosphites and relates more particularly to quaternary morpholinium phosphites which are suitable for various uses as wetting agents detergents, emulsifying agents, germicides, fungicides, textile softenerg-textile lubricants, dyeing assistants, antistatic agehts','texa1e spinning bath assistants, deodorants, etc.

It is an object of the present invention to provide a new group of quaternary morpholinum phosphites.

It is anotherobject of this invention to provide a method of manufacturing the said quaternary morpholinium PhoSPhites.

These and other objects and advantages will become obvious to those skilled in the art from the following disclosure. l '4 The compounds of this invention may 2? dfifined by the formula! i 1 CH OH R T 2 o :lnlnroi our-often:

R is an organic radical of 8 to 50 carbon atoms, containing as its main component, a lipophilic radical that contains from 8 to 20 carbon atoms. This radical may be present as an aliphatic hydrocarbon radical. In this form it contains from 10 to carbon atoms. It may be present in the form 0 ll 12' o 0.112,.) 2 wherein is an acyl radical containing from 10 to 20 carbon atoms, n is 2 to 3 and x is l to 10. Such a group is usually obtained by treating morpohline with an alkylene oxide and then esterifying the reaction product with a fatty acid containing from 10 to 20 carbon atoms. The lipophilic radical may be present as a substituent on an aromatic radical, i. e.

R on;

etc., in which case R" contains from 8 to 16 carbon atoms. It will be obvious to those skilled in the art that there are other types of lipophilic radicals that may also be present in the compounds covered by the present invention.

R is a lower alkyl group containing 1 to 12 carbon atoms.

2,815,345 Ce Patented Dec. 3, 1957 R is a lipophilic organic radical containing from 8 to 50 carbon atoms. The scope ofthis radical is the same as that given for R in the previous generic formula for the compounds of this invention. $nitable tertiary morpholines include, but are not limited to, N-lauryl morpholine, N-cetyl morpholine, N-octa-decenyl morpholine, N-soyal-yl morpholine, Nrstearyl morpholine, N-tetradecyl morpholine, the stearate of hydroxy ethyl morpholine, the oleate of hydroxy propyl morpholine, the laurate of polyoxyethylene morpholine, the palmitate of polyoxyethylene morpholine, the oleate of polyoxypropylene morpholine. The allgylene oxide chain in this la ter tu o s m eund may con a f m 1 t 1 y a oxide g ps. 2*hYs1rQ .=m. l zyl. m pholine, dodecyl' benzyl morpholine, etc. The soyalyl radical is a mixture of aliphatic hydrocarbons obtained by changing COQH t9 in the mixture of fatty acids occurring as glycerides in soyabean oil.

The products of the present invention are prepared by reacting a methyl alkyl hydrogen phosphite with a suitable morpholine derivative at a temperature ranging from about to 150 C. The preferred reaction temperature is from to 130 C. The reaction time will vary depending on the phosphite ester used. The dimethyl hydrogen phosphite is much more reactive and, accordingly, less reaction time is required.

The compounds of the present invention possess a unique property in that they readily absorb oxygen from the air. This property suggests that the quaternary morpholinium hydrogen phosphites of this invention are valuable reducing agents.

The following examples are given by way of illustration and are not to be taken as limiting the invention in any way.

Example 1 370 gms. of soyalyl morpholine and 111.5 gms. of dimethyl hydrogen phosphite were reacted on a steam bath for 23 /2 hours. The product on cooling set up to a stiff semi-solid, which was water soluble, giving clear foaming solutions.

Example 2 341 gms. of cetyl morpholine and gms. of dimethyl hydrogen phosphite were reacted over a steam bath for 23 /2 hours. The product was a soft solid at room temperature. It was water soluble yielding a clear foaming stable solution.

Example 3 30.5 gms. of Z-hydroxy-S-octylbenzyl morpholine and 11 gms. of dimethyl hydrogen phosphite were heated together in an oil bath at 110 to C. for 4 hours. The product was a soft resinous material, dispersible in water, giving opaque, foaming solutions.

a 3 Example 4 32 gms. of Z-hydroxy-S-nonylbenzyl morpholine and 11 gms. of dimethyl hydrogen phosphite were heated together in an oil bath at 110 to 125 C. for 6 hours. The product was a soft resinous material, dispersible in water, giving opaque, foaming solutions.
